Ex vivo evaluation of three instrumentation techniques on E. faecalis biofilm within oval shaped root canals.
The objective of the present study was to assess the effectiveness of reciprocating instrumentation in disinfecting oval-shaped root canals infected with Enterococcus faecalis. Forty-five human lower premolars were infected with a culture of E. faecalis (ATCC 29212) for 28 days. Five other teeth that were neither contaminated nor instrumented were used as controls. The 45 specimens were divided...
متن کاملComparison of Bacterial Leakage between 3 Different Root Canal Obturation Techniques in Oval Shaped Canals
Introduction: The purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. Methods: Sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. The teeth were sectioned at a 10 mm distance from the apex. After instrumentation, the teeth were divided into 3 gr...
متن کاملSurvival of Enterococcus faecalis in root canals ex vivo.
AIM The hypotheses tested in this study were that: (i) Enterococcus faecalis can survive long-term entombment in root filled teeth without additional nutrients, (ii) initial cell density influences the survival of E. faecalis in instrumented root canals and (iii) gelatinase-production capacity influences the survival of E. faecalis in root canals. METHODOLOGY The root canals of 150 extracted ...
متن کاملEfficacy of three thermoplastic obturation techniques in filling oval-shaped root canals.
The purpose of this study was to assess the efficacy of the thermoplastic filling techniques, Touch'n Heat®, TC® System and Tagger's Hybrid Technique, in oval-shaped canals at the apical third.Thirty-three human uniradicular lower pre-molar teeth were treated by the reciprocating movement technique and were subsequently split into 3 groups, according to the filling technique performed:Touch'n H...
متن کاملEffect of Passive Ultrasonic Irrigation on Enterococcus faecalis from Root Canals: An Ex Vivo Study.
Endodontic irrigation aims to clean and disinfect the root canal system. Passive ultrasonic irrigation (PUI) is based on the use of an ultrasound-activated instrument into the root canal filled with irrigant. The aim of this study was to evaluate, ex vivo, the effectiveness of PUI in eliminating Enterococcus faecalis from root canals. Seventy-five extracted human single-root teeth were used. Af...
